Abstract: 1439137 Cooling element for a furnace casing DIDIER-WERKE AG 15 Oct 1973 [19 Oct 1972] 48295/72 Heading F4B A cooling element, which is used with an evaporation cooling system of a blast furnace, comprises a cast iron plate 1 with internal cooling tubes 2. Refractory bricks 7 are embedded in and protrude from that face of the plate which is nearest to the fire in use. The cooling elements are contiguously arranged at the inside of the furnace. The protruding bricks 7 provide anchorage for refractory lining material (not shown), The outsides of the plates 1 are in contact with the inside of a metal casing (not shown) of the furnace. The cooling tubes 3, at their top and bottom ends 3, 4 extend through this casing. The bricks 7 may be tapered as shown or be rectangular, Figs. 5 and 7 (not shown), or may be roll-shaped.

Abstract: 1,108,610. Control of D.C. motors. CANADIAN INGERSOLL-RAND CO. Ltd. 15 Nov., 1965 [24 Nov., 1964], No. 48384/65. Heading H2J. [Also in Division G3] In a hoist for mine cars, means are provided for maintaining the cage in alignment with a station-floor despite variations in the load. Drum 12 is driven by motor 34 supplied from generator 40 whose field excitation is controlled by variable voltage device 46 connected to regulator 44. Tachometer generator 48 supplies negative feedback to the regulator 44. A current-limit circuit comprises shunt 52, and relay 54 which supplies a pre-set voltage to the regulator. When the cage is lowered on to a pair of chairs at the station floor, the speed-feedback signal is reduced to zero and the motor current will rise to the pre-set limit. The rope-tension is then at such a value as to prevent the cage from rising in the chairs when a car is removed, and, at the same time, slip between the drum and ropes is avoided.

Abstract: 1450957 Rollerways USS ENGS & CONSULTANTS Inc 22 Oct 1973 [20 Oct 1972] 49071/73 Heading B8A [Also in Division C7] In the heat-treatment of Si-steel strip' which is carried through the heat-treatment furnace by transport rolls having sleeves of rebonded fused silica, the rolls have pores or accretions of SiO 2  removed from the roll surfaces by selection of the annealing conditions and the grade of Si-steel annealed. Newlyinstalled rolls having surface pores are given a polished pore-free surface by annealing Si-steel strip at 1400-2000‹ F. under "dry" conditions (dew point 30‹ F. max.) for 24-72 hours. If, e.g. after subsequent "wet" annealing, the rolls surfaces begin to pick-up SiO 2  from the strip, it may be removed by annealing roughsurfaced strip (having at least 3% Si) at 1400- 2000‹ F., dew point 30‹ F. max., for 16 hours which removes the SiO 2  accretions by abrasion. The rough-surfaced strip may be strip which has been box-annealed or given a rough temper mill finish.

Abstract: 1475878 Automatic sequence control COAL INDUSTRY (PATENTS) Ltd 18 Oct 1974 [2 Nov 1973] 50987/73 Heading G3N An automatic sequence control system has a  plurality of limit switches LS I to 7 each of which selects the end of a particular stage in the sequence e.g. travel of controlled apparatus, to energize associated relays PR1 to 7 and thereby step a stepping switch SRI, SR2 to the next stage in the sequence. The system also includes a latching relay R2 which prevents automatic recycling at the end of the sequence. As shown, upon selection of automatic control by an auto-manual switch P1 to 5, an alarm is sounded for a time set by timer T 1 , then timer T 2  is energized. This moves stepping switch SR1, SR2 to the first stage of the sequence, turning off timer T2 and energizing solenoid 18A to move a lifting arm. This moves in stages so as to remove a lid on a coke oven, which is then filled under manual control and then the lid is replaced. In the first sequence stage, the arm moves near.the lid to open a circuit switch LS and energize timer T 2 , stepping the switch SR1, SR2 to the next position in the sequence. Each stage in the sequence is thus selected after completion of the previous stage. Relay R 2  also resets the switch SR1, SR2 to a starting position at the end of the sequence or if it is interrupted.
